Applicant's summary and conclusion
- Validity criteria fulfilled:
- yes
- Interpretation of results:
- readily biodegradable
- Conclusions:
- The modified MITI test (I) indicates a borderline case of ready biodegradability of 3-chloropropene with removal rates after 28 days of between 55 and 69 % based on BOD. Based on the available data ready biodegradability of 3-chloropropene is expected.
- Executive summary:
The ready biodegradability of 3-chloropropene was studied in a modified MITI test (I). Although the documentation of the test is poor the data are considered as reliable with restrictions. The concentration of the test substance at the start of the test was 100 mg/L. The concentration of the activated domestic sludge was 30 mg/L. The cultivation temperature was 25 °C. The test was performed for 28 days. The degradation of the test material was measured by monitoring the BOD, TOC and by analysing the test material using GC. The removal of 3-chloropropene (based on BOD) was between 55 and 69 % after 28 days. Analysis of TOC resulted in a similar level, whereas analysis of the test substance indicated that 95 % of the substance had disappeared. The substance was characterised as readily biodegradable on the basis of the MITI test (I).
